My check light comes on scanned system found several codes po443 evap,po135 o2sensors all banks,and egr vacuum regulator solenoid circuit can you advise me on next step


the codes should be addressed in the order they show up, so starting with the P0443 (it's a zero not an o after the P, the P refers to a powertrain code).
Have you replaced the purge valve itself, often times this will rectify the trouble.Open the gas cap after driving a while , do you hear a "whoosh" of pressure release? If so likely the valve itself is defective.Replace it reset the MIL and drive to see if light comes back on, if it does ,rescan to see if 443 is still present, if not then move on to new first trouble code.
(fyi)
To cause a P0443, there has to be a problem with the purge control CIRCUIT, not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following: Bad purge solenoid (internal short or open) Wiring harness chafing or rubbing another component causing short or open on control circuit Connector worn, broken or shorted due to water intrusion

I replaced evap vent solenoid & dtc came back


Here is the definition of the code and possible causes.

P0449 PONTIAC Description The Engine Control Module (ECM) monitors the Evaporative Emission System (EVAP) Vent Valve/Solenoid system wiring for opens or shorts.

When is the code detected?The Engine Control Module (ECM) has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Possible causes - Vacuum leaks, damaged hoses or improper routing
- EVAP system - Check fuel cap, canister, valves or components
- Faulty purge or vent solenoids
- Check connector and wiring
- Fuel saturated vapor canister
- Failed EVAP vent solenoid

P0446 code 1998 gmc jimmy how do I fix this? where is it located?


Hi there:

A code P0446 could mean one or more of the following has happened:
- Faulty vent valve
- Open, short or excessive resistance on Vent valve control circuit
- Blockage of vent valve
- Bad PCM




With a P0446 OBD-II trouble code, here are some things to try:
- Replace Vent valve
- Repair open, short, or resistance problem in control circuit
- Repair open, or short, or resistance problem in power circuit

- Replace PCM




Hope this helps.

Engine lite on. diagnositc code indicates purged valve C fault. What is this.


DTC P0443 - Evaporative emission control system Canister Purge control valve (CANP) or vapor management valve (VMV) circuit malfunction.
Your cars computer is telling you there is a leak. But most of the time when the system is smoke tested, the tech comes up empty handed. This is because the leak is intermittent. There are several solenoids that can do this on your evap system. The purge valve and the vent valve are the most common. Looks like it is going to be your purge valve.

That said, it could be any of the following:

Bad purge solenoid (internal short or open)
Wiring harness chafing or rubbing another component causing short or open on control circuit
Connector worn, broken or shorted due to water intrusion
Driver circuit inside powertrain control module (PCM) is bad


Code P0443 - Evaporative emission control system Canister Purge control valve (CANP) or vapor management valve (VMV) circuit malfunction. The PCM expects to see battery voltage when the solenoid is commanded off and voltage under 1 volt when the solenoid is commanded on.

Enabling conditions: Run engine off and running self tests to check this code. Blocking Action: This code can block the following monitors: Fuel Control, O2 monitor, Catalyst Monitor, misfire monitor. Testing: Check to see if the purge solenoid will block vacuum when it's off and pass vacuum when it's turned on. Typical resistance is 50 to 100 ω.

Hope helps.

Code 449? what is this,anyone. tks


Code po449 is for bad  solenoid vent valve.After replacing the valve  check for the   12 volts at the "pink" wire.
This error relates too

Probable Causes
1- Purge or vent solenoids defective.
2- Check connector and wiring.
3- Fuel saturated vapor canister.
4- Failed EVAP vent solenoid.

The cost of the vent solenoid valve is near to 30 bucks. And the valve is located near the gas tank.

Thanks. you can rate this solution and show your appreciation.

Hello. Your code indicates that your emission system is acting up. If you live in California, you might have a problem passing the next mandatory emmissions test. The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connector and wiring
3- fuel, saturated vapor canister
4- Failed EVAP vent solenoid

WHAT TO DO ABOUT TROUBLE CODES PO449 & PO141 ON 01 VENTURE


code is P0449

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:

4- Failed EVAP vent solenoid


A code P0141 may mean that one or more of the following has happened:
  • open or short to ground in the wiring harness
  • O2 heater circuit wiring high resistance
  • O2 heater element resistance is high
  • Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.
Possible Solutions
  • Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
  • Repair short or open or high resistance in wiring harness or harness connectors

I don't know how the above could have any effect on temperature. Is the vehicle full of coolant? In my opinion you have two different issues
